Perhaps when using turn tracker (or similar), an aura appears at the player's start location displaying total movement available (given system of choice). Then, as they get farther away, a second invisible aura token follows them, shrinking as they get toward the boundary to indicate how much further they can move. Of course, that implies issues with moving around corners... To do that, you'd need to either implement pathfinding (nope) or make some macro button mark an intermediate step, but that seems really excessive just to move around... Maybe some hotkeyed bookmarklet-style things? That might be the easiest way to do it... As for PF diagonals... Is it possible to use the API to scale a translucent token? Perhaps you could precompute an image that looks like a hunk of bismuth (you know, with the nested squares) that increases in transparency as you move outward and then hope that one of them falls roughly at the boundary you're on? blech... I can see why this hasn't happened yet...
